What a pity you are leaving so soon . I wish you could stay a few more days . Sir , can you deliver a speech for us ? 
 Dear friends . Here , I wish to say a word of thanks for holding this send-off party for me . Actually I didn't expect at all for this . I owe a lot to all of you here . It's been 5 days since I came to visit here . Time really flies . I feel grateful for your welcome and help in the five days . I will miss you while I am leaving . Let's keep in touch in any way . What's more , to the success of our face-to-face meeting , to the upcoming cooperation of our two companies , bottom up !
